FiTech EFI system

I also experience starting and dying after a second only when it's really hot. If I'm driving it, and then pull into a store for a minute. And then get back in it, it will start and then die. But if it's cold, it will start and run no problems. I was thinking it might be heat related, and thus related to the FCC mounted in the really hot engine compartment and vaporizing the fuel in the canister.

There's a few things I've found that have an effect. First and foremost was interference with the ignition - I had an issue due to a burned wire and fixing that helped a heap.

The other has been the IAC open during crank. It's listed under idle control as 'CRANK IAC'. I had to up mine quite a bit to get it to fire off during hot restarts.
